Create 3D Contours with our Relief Shading Feature

3d Shading Demo 2016

With relief shading, the map is drawn as a 3D model, with lighting from the east or west. The effect is to greatly enhance the perception of the landscape, especially when you stand back and look at the map from a distance. There are no perspective effects, so the shaded map can be used for measurements exactly like a normal map. The only disadvantage is that some of the detail in the darker areas of the map is harder to read.

The Relief Settings dialog (accessed by clicking the Settings button next to the Relief shading option in either the Print dialog, or the Image export dialog) is shown below.

panelThe Brightness controls the overall brightness of the image. The default value is 80%. This means that a horizontal area of the terrain is drawn slightly darker than normal, which gives a better highlight the brighter parts of the image. If you set the brightness to 100, the flat areas are drawn with normal brightness (i.e. a flat white area still appears white).

The Contrast sets the variation between east and west facing slopes. Increasing the value gives a more dramatic effect, reducing it gives a more subtle effect. The default is 150. The contrast is automatically scaled by the maximum slope in the image. A contrast setting of 100% causes the point of maximum slope to be drawn as black. If your scene includes abrupt cliffs, increase the contrast to bring out the terrain features in the flatter areas. A value of zero removes the shading completely.

Occasionally, the landscape may appear to you to be ‘inside out’ (i.e. the valleys appear closer to you than the hills.)  This is simply an optical illusion, not a problem with the software. Changing the direction of lighting from west to east or vice versa will make it pop back the other way.

Which map scale would suit you best?

HD-Great-Britain-Maps-lrOrdnance Survey (OS) is the mapping agency of Great Britain, providing detailed high quality maps of the country. First established in 1791, the Ordnance Survey eventually mapped Great Britain at a scale of one inch to the mile. Drawn on a larger scale than the final printed maps – two inches or six inches to the mile – these old maps show incredible detail.

In 1854 a scale of 25 inches was initiated, and by the end of the 1800s all cultivated areas were mapped at this scale, which showed every building in outline ground plan to a high standard of accuracy.

In our technologically advanced age, Memory-Map was the first company to licence OS map data to produce digital maps for outdoor recreation and their OS Landranger 1:50,000 and OS Explorer 1:25,000 maps look identical to the printed Ordnance Survey versions.

The main difference between the two map products is scale – the number of times that you would need to magnify the map for it to be the same size as the real world; or the number of times that the real world has been reduced in size to become the map.

OS Explorer (1:25k) Mapping

The OS Explorer Map is at 1:25000 scale (so 4cm on the map equals 1km in the real world). It shows great detail of the area the map is covering including footpaths, rights of way, open access land and the vegetation on the land. This is the map you would use for your outdoor activities such as walking, horse riding and off-road cycling.

OS Landranger (1:50k) Mapping

The OS Landranger Map is at 1:50000 scale (so 2cm on the map equals 1km in the real world). The map covers a larger area than the OS Explorer Map, but not in as much detail. You’ll still find footpaths, rights of way and some tourist information features on the map. While some of the detail is lost, such as open access land on this map – it is still possible to use it when out walking for navigation with your compass. This is the map you would use for days out or short breaks and even road cycling as a larger area is covered.

Using Memory-Map is the easiest and quickest way to get Ordnance Survey Explorer and Landranger maps onto your PC, iPhone, iPad, or Android device; turning your mobile into an outdoor GPS to make navigation safer, easier and more fun.

If you’re a history-buff, Memory-Map also have a complete selection of historical Ordnance Survey maps available for use across multi-platforms, either in singular packages or combined.

The long road to mapping Great Britain.

This month sees the release of the latest updated Ordnance Survey maps of Great Britain, which have been in existence for 225 years. But their genesis was even earlier.

The officially recognised date as the birth of Ordnance Survey, Britain’s mapping agency, is June 1791 but it has its roots in military strategy; the mapping of the Scottish Highlands following the Jacobite rebellion of 1745.

William Roy, a 21 year-old engineer, was tasked by the Board of Ordnance (the defence ministry of the day), with the initial small-scale military survey of Scotland, the first government-made survey of a substantial tract of the British Isles.

Beginning in 1747, it took eight years to complete what was known as the Great Map at a scale of 1:36 000 (1.75 inches to a mile). Roads, hills, rivers, types of land cover and settlements were recorded. Roy himself described it as more of a “magnificent military sketch than a very accurate map of the country.”

The surveying parties relied on simple surveying compasses to measure the angles, and chains up to 50 feet long to measure distance between important features. Much of the rest was sketched in by eye. Nevertheless, the map was a powerful tool as part of a broader strategy to open up access to the Highlands.

In 1763, 1766 and 1783 Roy made proposals for a complete official survey of Britain but all these proposals failed because the cost was considered excessive.

The real start of work which can be recognised as ‘Ordnance Survey’ came in 1783-4, when the Royal Societies of London and Paris worked out the relative positions of the astronomical observatories in their two cities by connecting them by a system of triangulation. Until the recent advent of GPS, triangulation was the universal means of providing a skeleton for controlling survey operations, and was the only feasible way of measuring distance across water and other obstacles where ground measurement by chains or tapes was impractical.

As the leading geodesist of the day the English part of the operation came under the Roy’s direction. His lifelong ambition was to produce a superior map of Britain, unparalleled in its accuracy and by the time of his death in 1790, with the London-Paris triangulation completed, he was thinking of using its extension as a basis for further survey work in Britain.

The Master-General of the Ordnance, who was sympathetic to Roy’s ideas, authorised the expenditure of £373.14s of national funds to purchase a newly-designed theodolite on 21st June 1791 and this date has since been taken as the official ‘foundation date’ of the Ordnance Survey.

By 1823 it had covered much of Britain.

The latest OS maps of Britain are now available across many platforms including the TX4 GPS and will soon be available for 7” tablets. You can even step back in time with historical OS maps from the 1800s, 1900s, 1920s and 1940s and see how OS maps have changed over time. All are available now from Memory-Map.
